Capcon Supply Siphonic Drainage to Major National Project


Capcon Engineering helped to deliver the “Dublin Waste-to-Energy” project at Poolbeg – which is of national significance and is being led by Dublin City Council in conjunction with Covanta, a world leader in sustainable energy. Here’s the science bit – our work involves installing over 2km of High Density Polyethylene Pipework using a Valsir Rainplus Siphonic Drainage System over nine Primary and nine Secondary Systems. Read on to learn more about the work, how the project is progressing and what’s involved in terms of delivery by Capcon.

The Dublin Waste-to-Energy Project

The development located at Poolbeg, Dublin Port, will have the ability to generate enough power for 80,000 homes as well as enough heating for 50,000 homes – generated from up to 600,000 tonnes of waste that would ordinarily be destined for landfill.

The project is projected to be fully commissioned by the end of 2017. Covanta, experts in waste-to-energy, are currently in recruitment mode, looking for people to resource the facility – which is set to start-up at the beginning of 2017.

Siphonic Drainage System

Capcon specialises in Rainwater Drainage Systems both Siphonic Drainage and Gravity Drainage.

We are providing a state-of-the-art 2km HDPE Pipework for the Waste-to-Energy facility in Ireland through a Public Private Partnership (PPP) between the two promoters – Dublin City Council and Covanta. Capcon was chosen due to our extensive experience in this area. We were able to guarantee a high quality install by bringing the Siphonic Drainage System all the way to ground level. This was something our competitors could not do, as other proposals involved breaking the system (and therefore the Siphonic Action) half-way up the building, thereby hugely reducing the efficiency of the solution. The Siphonic System originated in Scandinavia over 40 years ago and has been seen in Ireland since the early 90’s. Costs savings of up to 45% can be made with this system as it enables the pipes to run horizontally within the building thereby reducing underground drainage. Take a look at our short video for more details.

At Poolbeg, by enabling the drainage system to reach ground level directly we can greatly reduce both the capital outlay and the running costs for the facility. In terms of the initial investment, it requires lower labour costs and a reduction in the cost of materials that would normally have been required with a conventional system.

How Are We Doing It?

Our highly skilled engineers have designed the pipework to be installed at a 12⁰ gradient whilst still performing to Siphonic Standards EN 12056-3:2000 & BS 8490:2007. This highly complex install allows the system to operate at maximum capacity.
